Definitions

  • the present invention relates to a method for trueing grinding disks having an outer layer with diamonds or cubic crystalline boron nitride using a driven trueing roll and an additional trueing aid.
  • Profiled diamond grinding disks are, during production thereof pre-profiled by a pressing step and subsequently ground with ceramic disks such as silicon carbide grinding disks. This is, however, an expensive method, and subsequent profiling must be carried out by the producer of the disk. Therefore, it is already known to provide for the use of profiled grinding disks with diamond or cubic crystalline boron nitride in galvanic binding only one layer of grain, whereby however such disks after loss of their exact form cannot be used any longer.
  • trueing respectively profiling rolls of steel or hard metal is known for the trueing and profiling of corundum or silicon carbide grinding disks with ceramic binding.
  • profile rolls of silicon carbide in ceramic or bakelitic binding for the trueing of grinding disks (U.S. Pat. No. 2,456,762) which are, however, usable only for grinding disks with diamonds in ceramic or bakelitic binding material.
  • Diamond tools, such as diamond trueing rolls are usually used for trueing of grinding disks with corundum or silicon carbide, which tools, in view of their greater hardness, permit to provide such grinding disk with the necessary profile.
  • the method according to the present invention for trueing a grinding disk having an outer layer with diamond or cubic crystalline boron nitride during rotation thereof at a predetermined circumferential speed comprises the steps of engaging this outer layer with a driven diamond trueing roll and spaced from the trueing roll with an additional driven trueing disk rotating with a relative peripheral speed of 0.5-6 meters per second relative to the peripheral speed of the grinding disk. If such a relative speed is provided between the trueing disk and the grinding disk profiled by the diamond trueing roll, in the magnitude of preferably 1 meter per second, then this relative speed is sufficient to assure that the grains of the grinding disk will project sufficiently beyond the binding material thereof.
  • the diamond trueing roll can thereby be rotated with a different speed than the grinding disk, whereby it is usually advantageous during the pre-profiling of the grinding disk to rotate the latter and the diamond trueing roll in the same direction, whereas during finish profiling of the grinding disk the latter is preferably rotated in a direction opposite to the rotation of the trueing roll, to thereby provide already a certain projection of the grains of the grinding disk beyond the binding material. This grain projection is then increased by the with smaller relative speed rotating trueing disks to the desired dimension.
  • the method according to the present invention has the additional advantage that it is possible during grinding of a workpiece to carry out a continuous re-profiling to the necessary extent.
  • the additionally driven trueing disk has an outer layer of ceramically or bakelitically bound silicon carbide or an outer layer of ceramically or bakelitically bound corundum.
  • the use of such a material has the advantage that the trueing disk will continuously adapt itself to the profile of the grinding disk, which is continuously produced by the diamond trueing roll so that the trueing disk will not subsequently enter into the profile of the grinding disk to thereby, for instance, remove the points of toothed profiles.
  • FIGURE of the drawing schematically illustrates an arrangement for carrying out the method according to the present invention.
  • the grinding disk 1 shown in the drawing is provided with an outer layer of diamond or cubic crystalline boron nitride and rotated in clockwise direction as indicated by the arrow 3.
  • a diamond trueing roll 4 is provided for trueing and profiling the grinding disk 1, and the trueing roll 4 rotates in counterclockwise direction as indicated by the arrow 5, whereby preferably a relative speed between diamond trueing roll 4 and the grinding disk 1 is maintained.
  • the diamond roll 4 is moved against the periphery of the grinding disk 1 in the direction as indicated by the arrow 6.
  • a trueing disk 7 is provided as additional trueing aid, and the disk 7 is rotated in clockwise direction as indicated by the arrow 8.
  • the trueing disk 7 is pressed with a constant force in the direction of the arrow 9 against the periphery of the grinding disk 1 to engage the periphery of the latter along a line spaced in direction of the arrow 3 from the line of engagement between the diamond trueing roll 4 and the grinding disk 1.
  • the trueing disk 7 has an outer layer of ceramically or bakelitically bound silicon carbide or corundum.
  • the trueing disk 7 is rotated for instance with a peripheral speed of 29 meters per second, when the grinding disk is driven with a peripheral speed of 30 meters per second, so that the relative speed between grinding disk 1 and trueing disk 4 is 1 meter per second.
